Good idea bad execution - Alien Gear Holsters ShapeShift Glock Core Carry Holster Pack

I really love some of the features of this holster, like adjustable retention without a tool and the incredible ease of changing from owb to iwb. But where the holster falls short is it's concealability and comfort. I'm 5'9", weigh 140 and this thing still sticks me in the gut aiwb. The worst thing is it isn't the gun the sticks me in the stomach it's the flap on the holster that is ironically there to provide comfort. Not only that but it's bulky and conceals terribly. I absolutely would not recommend this holster
